FSK Tape Description


FSK insulation tape is reinforced with fiberglass scrim with a foil, scrim, and Kraft laminate backing. The foil layer provides a reflective barrier that helps to prevent heat loss, the scrim layer provides reinforcement, and the kraft paper layer provides a backing that helps to keep the adhesive from sticking to itself.

FSK insulation tape adheres well to FSK faced insulation materials and other building materials. The aluminum foil layer helps prevent moisture vapor from migrating through the insulation, reducing the risk of condensation and mold growth. The foil reflects radiant heat, potentially helping to improve the thermal efficiency of the insulated space. The scrim reinforcement adds strength and prevents the tape from tearing easily during installation.

FSK insulation tapes combination of strong adhesion, vapor barrier properties, and durability makes it ideal for creating a tight seal and improving the overall performance of your insulation system.

Tape Applications:

FSK insulation tape is primarily used to seal seams, joints, and overlaps between FSK faced fiberglass duct wrap insulation boards, pipes, or other insulation materials. This creates a continuous vapor barrier and helps prevent air leaks, improving the overall thermal performance of the insulation system.

Tape Features:

  • Scrim layer bends with the primary facing providing integrity to the insulation and a strong, finished, appearance.
  • Release liner provides easy removal for efficient application on the job site.
  • High-tack synthetic rubber adhesive forms an instant bond.
  • Moisture-, mold-, and UV-resistant design.
